Hi, analysts!👋
I've got another useful #cheatsheet for you today.

🛠 How does SQL execution order work, and why is it so important? 🛠

Knowing the order is crucial for your query efficiency. Focus on optimizing early steps in the query.

Optimization tips:

📌 Maximize the WHERE clause:
Executed early, it reduces the data set before further processing.

📌 Filter before a JOIN:
Use subqueries in the FROM statement to limit rows.

📌 Use WHERE over HAVING:
Move conditions to WHERE when possible for earlier execution.

📌 Don't rely on LIMIT, OFFSET, and DISTINCT for optimization:
These occur at the end and don't significantly impact performance.

Understanding how SQL works under the hood ensures your optimization efforts are effective. Tailor these tips to your unique use case for the best results.🚀

Hi, analysts!👋

This month we launched a survey to find out more about our subscribers' work experience. Our survey showed that about 44% of our subscribers are professionals with less than 3 years of experience. About 30% are between 3 years and infinity. 🛸

We are all so different, but we have at least one common goal - to show everyone that analysts are superhumans!🦹‍♀️
